Additive-free MXene inks and direct printing of micro-supercapacitors
(2019)
Direct printing of functional inks is critical for applications in diverse areas including elec-trochemical energy storage, smart electronics and healthcare. However, the available prin-table ink formulations are far from ...
Structural, optical, and electrical properties of silver gratings prepared by nanoimprint lithography of nanoparticle ink
(2021)
A facile method for fabrication of silver gratings using silver nanoparticle ink and nanoimprint lithography is investigated. The properties of silver nanoparticle ink grating and planar samples, with and without a PMMA ...
Association of perceptions of artificial light-at-night, light-emitting device usage and environmental noise
(2022)
Exposure to artificial light-at-night (ALAN) is increasing globally, and there are concerns around how ALAN may impact sleep, psychological and physical health. However, there is a lack of evidence in the literature on how ...
Comparison between the amorphous and crystalline (A15) phases of Nb3Ge
(American Physical Society, 1978)
A comparative study on the superconducting and the normal-state properties of the amorphous, low-Tc (3.9 K) and the crystalline, high-Tc (2.18 K) phases of Nb3Ge suggests that changes in the strength of electron-phonon ...
Magnetization and 57Fe hyperfine fields in Y2Fe17Z3-??(Z=H, C, or N) interstitial compounds
(American Physical Society, 1992)
Measured magnetization and 57Fe hyperfine fields at T?_0 K for Y2Fe17 and Y2Fe17Z3-??, with Z=H, C, or N and ???_0.5, are analyzed to determine the influence of the interstitial atoms on the 3d magnetism. All are weak ...
Enhanced energy product in Y-Co-Fe magnets intermediate between Nd-Fe-B and ferrite
(2015)
The hysteresis of ball-milled Fe-doped YCo5 powder has been optimized by controlling the temperature and time for rapid annealing under vacuum and argon. The crystallite size is only 25 nm; yet, it has been possible to ...
1/f noise in MgO double-barrier magnetic tunnel junctions
(2011)
Low frequency noise has been investigated in MgO double-barrier magnetic tunnel junctions (DMTJs) with tunneling magnetoresistance (TMR) ratios up to 250% at room temperature. The noise shows a 1/f frequency spectrum and ...
X-ray spectroscopic studies of the electronic structure of chromium based p-type transparent conducting oxides
(Trinity College Dublin. School of Physics. Discipline of Physics, 2018)
In this thesis the electronic, optical, electrical, and mechanical properties of two
p-type transparent conducting oxides will be explored, primarily by spectroscopic
techniques. The initial chapters outline how the ...
Scanning tunneling spectroscopy study of the electronic structure of Fe3O4 surfaces
(2006)
Scanning tunneling spectroscopy (STS) experiments were performed on the (001) and (111) surfaces of single crystalline magnetite. Room temperature spectra exhibit a ~0.2 eV gap around Ef. The importance of perfect surface ...
Laser-induced failure modes in plasmonic thin films
(Trinity College Dublin. School of Physics. Discipline of Physics, 2019)
In order for the areal density of magnetic hard-drives to continue increasing, it is necessary to improve upon current recording technologies. The proposed next-generation magnetic recording process, heat-assisted magnetic ...
